By blending the capabilities of Ningbo Guangji Lighting Technology Co., Ltd. and Jiangsu Sass Lighting Technology Co., Ltd., we provide a unified supply system. This ranges from highly customized smart solar bollards for landscape architecture to high-performance indoor LED ceiling panels, spotlights, and bulbs. Guided by our core principles of Green, Energy-Saving, Eco-Friendly, and Technology-Driven manufacturing, we construct high-efficacy, glare-free, and long-lifespan fixtures engineered to meet the strictest standards of European, American, and Asia-Pacific markets.

"Green Technology, Brighter Future. We are committed to the vision of enjoying an energy-saving future through rigorous engineering, transparent compliance, and direct factory-to-port supply chain efficiency."

Ningbo Guangji and Jiangsu Sass Production Plant Overview

China Factory Supply Chain & Regional Manufacturing Advantages

Operating from the heart of the Yangtze River Delta electronics hub, our production network offers unparalleled material access, speed-to-market, and manufacturing precision.

The Zhejiang-Jiangsu Logistics & Components Hub

Our strategic location in Cixi, Ningbo, and our modern facilities in Jiangsu put us in the middle of China's top lighting components ecosystem. We source high-grade raw aluminum, driver integrated circuits (ICs), high-transmittance PMMA diffusion plates, and high-efficiency LED chips (such as Sanan, Epistar, and Lumileds) locally. This dense supply network reduces transportation costs and lead times, while keeping our production schedules insulated from global supply disruptions.

Proximity to both the Port of Ningbo-Zhoushan and the Port of Shanghai allows us to offer flexible shipping terms (FOB, CIF, EXW) with minimal overland shipping delays. This ensures fast international delivery for bulk orders and time-critical project shipments.

Advanced Manufacturing and Quality Controls

Our factories use high-speed automated SMT (Surface Mount Technology) assembly lines, automated solder paste inspection, and robotic assembly stations. This precision minimizes defect rates to less than 150 PPM (parts per million). Our ISO 9001 certified facilities conduct automated optical testing (AOI), high-voltage isolation checks, and multi-stage burn-in tests on every batch of LED ceiling lights.

By keeping aluminum die-casting, stamping, driver manufacturing, and final optical assembly in-house, we control the entire production process. This vertical integration allows us to optimize manufacturing costs and pass those savings directly to our partners.

Solving the Complexities of Global Enterprise Procurement

How we address the technical requirements, risk mitigation, and compliance needs of corporate buyers, engineering contractors, and OEM brands.

1. Strict Certification Compliance

Our entire catalog is updated to match the latest global directives. We supply new ErP (Energy-Related Products) compliant products for Europe, along with CE, RoHS, and SAA certifications. This ensures quick customs clearance and avoids commercial liability.

2. Customization and SKD Options

For regions with high import tariffs, we offer Semi-Knocked-Down (SKD) component kits. Our engineering team provides PCB design layouts, plastic housing molds, and optical diffusers to help partners run local assembly operations cost-effectively.

3. Direct OEM/ODM Integration

We offer full support for custom packaging, laser etching, private labeling, and customized electrical parameters (such as multi-Kelvin dip switches, dual-voltage drivers, or integrated microwave motion sensors).

Compliance, Certification, and Advanced Testing Protocols

Every production batch undergoes strict laboratory verification to meet global electrical and photobiological safety standards.

New ErP Directive

Fully compliant with EU Regulation 2019/2020, offering high-efficiency light sources with excellent color maintenance factors.

CE & RoHS Standards

Guarantees safe electromagnetic compatibility (EMC), low voltage safety (LVD), and strict restriction of hazardous chemical substances.

Thermal Management

Fixtures are engineered using advanced thermal simulations to keep junction temperatures low, ensuring a long L70/B50 lifetime exceeding 50,000 hours.

Photobiological Safety

Flicker-free performance and EN 62471 certification protect eyes from blue light hazards, making these products ideal for schools, offices, and homes.

Technical FAQ and Sourcing Insights

Essential technical details, manufacturing facts, and sourcing advice for international wholesale buyers and procurement directors.

What are the shipping routes and ports used for export?
Our factories are located in Cixi, Zhejiang, and Jiangsu province. This allows us to ship directly out of the Ningbo-Zhoushan Port and Shanghai Port. Both ports offer daily routes to major global destinations across Europe, North America, and Australia.
How do your products comply with the new EU ErP regulations?
Our lighting fixtures are engineered to meet the latest Energy-Related Products (ErP) directives. We use high-grade LEDs and constant-current drivers that achieve excellent lumen-per-watt efficiency, keeping standby power consumption under 0.5W.
Do you offer SKD or CKD shipping options?
Yes. We offer Semi-Knocked-Down (SKD) and Completely Knocked-Down (CKD) kits for regional distributors and manufacturing partners. This helps reduce import duties and shipping volumes while supporting local assembly lines.
What custom options are available under your ODM services?
We provide full ODM support. This includes custom casing dimensions, customized driver PCBs, adjustable color temperatures (3000K/4000K/6500K via DIP switches), integrated motion sensors, and smart controls (Tuya, Zigbee, BLE mesh).
How do you manage thermal dissipation in thin ceiling lights?
We use high-conductivity aluminum PCBs (up to 2.0 W/m·K) and die-cast aluminum heat sinks. This design pulls heat away from the LED chips, maintaining a safe junction temperature and extending the lifespan of the fixture.
What is the minimum order quantity (MOQ) for custom branding?
For custom packaging and laser branding, our standard MOQ is 1,000 units. For generic white-box packaging, we offer lower minimums to support new product launches and pilot projects.
